The Yankee army Police System--Gen. Morgan's plans Betrayed.Among the new institutions characteristic of that nation which has been introduced by the Yankees is an "Army Detective System." The Cincinnati Commercial contains a detailed and circumstantial account of a successful attempt by a Kentucky traitor to install himself as a spy for Gen. Morgan in February last, while he was the chosen instrument of the Federal detectives, under the notorious Truesdale. The party now assumes the name of Johnson; but Morgan and his officers at least know his real name. The treachery was entirely successful, and the spy both carried and brought letters for Morgan and his family, which letters were duly read at Nashville by the detectives before they were delivered; and thus, and in other ways, Morgan's plans were communicated to the foe. This revelation should furnish a warning to our officers not to take any but the most tried and faithful men into their confidence. In this instance, the spy saved Nashville when it was weak by false reports to Morgan of its strength; caused the capture of Capt. Chariton Morgan at Lexington; exposed Gen. M.'s plans, and possibly led to the later disasters which befell his command. The following is the spy's narrative, un blushingly furnished by himself:
Truesdale, whom the Yankees denounce as an infamous swindler and scoundrel, takes the matter in hand:
Note from Chief of Police to Gen. Rosecrans.General: I have sent Johnson back with information not very inviting to Gen. Morgan; yet I am of opinion the latter will make a raid upon some point in your command within ten days. He has a chain of scouts this morning extending from Stone's river perhaps into the city, all the way through to Lebanon, Greenville, Smithville, and McMinnville, his general headquarters. One hundred of his men were at Stone's river last night, I am informed.
Chief of Army Police.
The spy Johnson was sent back to Morgan with proper instructions, made his trip successfully, returned and reported as follows: I left Nashville February 9, and stayed at Stewart's Ferry that night; next morning went four miles beyond Beard's Mill; next day went five miles beyond Liberty. On the 12th went to McMinnville, to Gen. Morgan's headquarters. When I went into his office the General was not there, but his brother, Charlton Morgan, was in. He said to me, "Is it possible that you have got through." He then called one of the boys and sent word to the General that a man wanted to see him on important business. The General came over, and as he came in said to me: "Mr.--,I am very glad to see you." He then turned to his brother and said: ‘"I told you he would go through, Chariton. I am hardly ever deceived in a man."’ I told him I had some things for his wife from Mrs. Dr. Cheatham. He then invited me over to Dr. Armstrong's, where he was boarding. We went in and he introduced me to his lady, saying, ‘"Here, my dear, is the gentleman I told you of; he is just from Nashville."’--She asked me to be seated, and the General then asked me for information about Nashville. I told him that they were receiving heavy reinforcements there — that there were fifty-seven transports lying at the leves, loaded with troops and provisions.--He asked me if they had not been burned yet. I told him they had not. He says, ‘"Well, they will be."’ He asked me when I would be ready to go to Nashville again; and I told him that I was ready at any time. He asked me if I did not want some money; I told him I did, and he gave me one hundred dollars--part in Confederate, and part in greenbacks and Tennessee money. He then said be wanted me to leave on Sunday or Monday for Nashville. On Monday I started for McMinnville. He told me to find out how many-troops there were here, where they were going to, and how many transports there were here and their location.--Also, how many gunboats there were here, and whether they lay above or below the railroad bridge. He said for me to get all the information I could of the movements, location and number of the army. Monday night I stayed at Mr. Bradford's, five miles the other side of Liberty; next night stayed at widow Buchan's, five miles beyond Lebanon; next stayed two miles this side of Green Hill; and the next day, (Thursday,) came to Nashville. While I was in the General's office at McMinnville, Colonel Clerk, commanding Duke's brigade, came in and asked the General if the troops could be paid off before going into Kentucky. Morgan said they could be paid. He asked the Colonel if he wanted any money. The Colonel said yes, that he wanted commutation for fifty days. In marching they do not issue rations. Heard Major Steel say that the command would be at Sparts in the morning.--Learned from officers at McMinnville that there were near 25,000 troops at Tullabours, that they were fortifying there, and at Manchester and Shelbyville, and that Breckinridge was at Manchester. While at McMinnville I saw the telegraph operator, who invited me to his office. He was just sending to Bragg the news I had brought. While in his office he received a dispatch from either Richmond or Charleston, saying that France had interfered, and that commissioners were to meet in Central Mexico.
Then follows, in the original, a letter from Mrs. Gen. Morgan to her sister, and other letters, and the spy proceeds with his statement: Not only were the ladies thus wickedly deceived by "our man," but Gen. John Morgan was so completely sold by this — his own — spy that we suppose he has had his ears measured repeatedly of late to ascertain their increased length. The following facts will show how Morgan's brother lost his liberty, and "our man" came within view of a halter. Coming into Nashville on his second trip, he brought a letter from Capt. Clarence Morgan, the General's brother, addressed to their mother in Kentucky, to be mailed at Nashville. This letter advised the mother that its writer would be at Lexington, Ky., upon a certain day, and desired her to meet him there. This letter contained the following note from the devoted Chariton Morgan to his lady love, as it would seem:
